SPECIFICATION forming part of Letters Patent No. 397,049, dated January 29, 1889.

Application filed March 6, 1888. fierial No. 266,377. (No model) To ctZZ whom, it may concern:

Be it known that I, BAYLUS CADE, a citizen of the United States, residing at Louisburg, in the county of Franklin and State of North Carolina, have invented certain new and useful Improvements in Railway-Telegraphs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to telegraphy.

The obj eet is to provide simple and effective means whereby telegraphic communication may be established between moving trains and the stations along their tracks, or elsewhere.

The invention consists in a conductor of electricity comprising permanent magnets and pieces of attractable metalsuch as soft iron-placed in contact and suitably insulated.

Furthermore, the invention consists in a conductor of electricity comprising permanent magnets and pieces of attraetable material placed alternately and in, contact with each other and an insulatiugbaiul or belt inclosing the same, and to which they are suitably fastened.

Furthermore, the invention consists in a conductor of el j+etricity composed of permanent magnets and pieces of attraetablemetal such as soft iron-alternately placed and in contact with each other, and a suitable band or covering of insulating material in which said pieces are inclosed each piece being secured at or near its center to .the upper portion of the insulating band or belt by means of a rivet or other fastening exposed above the surface of the insulation.

Furthermore, the invention consists, in combination with a car or other movable body carrying an idle-wheel, cam, or projection, of a conductor of electricity composed of permanent magnets and pieces of soft iron arranged alternately and in contact with each other, and an insulating band or belt inelosing said pieces, the conductor passing above said idlewheel or similar device, for the purpose of breaking the contactbetwcen the pieces of metal within the band.

Furthermore, the invention consists, in

combination with a car or other movable body, of metal brushes carried by said car or movable body and an idle-wheel or projection, also carried by said car and placed between said brushes, a conductor of electrieity, composed of alternately-arrangedpermanent magnets and pieces of soft iron placed in contact with each other, and an insulatingcovering in which said pieces are inclosed, each piece being secured therein by a conductible metal fastening exposed above the surface of the insulation, said conductor being so placed that its metal fastenings will be in continual contact with the brushes carried by the car, the conductor passing above the idle-Wheel, cam, or projection, in order to break the contact between the magnets and pieces of soft iron.

F urthermore, the invention consists in various novel details of construction hereinafter fully set forth.

In the accompanying drawings like letters of reference indicate corresponding parts in all the figures, in which Figure 1 represents a car in side elevation, the metallic brushes being in contact with the electrical conductor, the conductor passing above an idle-wheel depending from the car between the metallic brushes. Fig. 2 represents a plan view of a portion of the electrical conductor alone, showing in dotted lines the pieces of soft iron and permanent magnets in contact with each other, and also showing the metallic fastenings exposed above the surface of the insulating-barid. Fig. 3 represents a vertical longitudinal sectional view of a portion of the electrical conductor alone, showing the insulating band or belting, the pieces of soft iron, and the permanent magnets in contact with each other, and also the metallic fastenings 'n'ojecting through the upper layer of insulating material. Fig. at represents a vertical sectional view of a portion of the conductor passing above the idlewheel, cam, or projection, in order to break the contact between the pieces of metal.

A designates a car of ordinary construction, upon opposite ends of which, preferably to the trucks, are secured metallic brushes B B, depending therefrom, being insulated from. the car and connect-ed with an ordinary telegraphinstrument placed within the ear. A conductor of electricity, is laid alone the road-lmd beside the track in such position that its upper su rlj'aee will be in continual eontaet with the brushes l; 1;. This conductor is termed ot' a series of 1')ern1anent magnets, N b e, and pieces of attrz'letal l.e metal, (1, alternately arrangt'ml. within a (covering, of rubber belting or other suitable insulating material. To the upper laee ot' thiseovering the magnets and pieces et' attraetable metal are SGCIH'UI, preferably byrivcts 1-, each piece being fastened at or near its center to permit its ends to have free movement when the position of the conductor is disturbed.

Depending from the car at a point between the brushes is provided an idle-wheel, cam, or projection, (I, over which the conductor passes. 'hen the eondi'letor is raised by this idle-wheel during motion of the ear, the magnets and pieces of attraetable metal at this pointwithin the conductor are scparatml from each other, as shown in Fig. 4, thus breaking the circuit. As soon as that portion of the belt is permitted to assume its normal position the pieces of metal are again brought in contact, this being insured by the attrz'ietion between the magnets and the attractable metal, the elasticity of the belt allowing the metal to be in continuous contact, notwithstanding the fact that the pieces are riveted to the belt. The metallic brushes beingin contact with the upper face of the conductor, they are consequently at all times in direet contact with one or more of the metallic fastenings exposed thereon, and the circuit in the conductor being, broken between the brushes by the dislocation of the metallie pieces the current oi electricity conveyed by the conductor is caused to pass through the car by means of the connection between thebrushes. Thus a continuous line is provided from one end of the track to the other, the ear being at all times, whether at rest or in motion, directly within the eircuit, the circuit of the line being broken at no place except ltieneath the ear or at the point oi? raising the eon ductor above the idle-wheel.

Having thus .t'ully deserilwd my invention, what I claim as new, and desire to secure by Letters lz'l tent, is-

1. A eomlnetor of eleeti-itdty, comprising permanent magnets and pieces of attractable metal placed alternately and in contact with each other and suitably insulated, substantiall y as set Forth.

2. In a cmiduetor of electricity, the combination of permanent magnets and pieces of attraetable meta-l placed alternately and in contact with each other and an insu lating'bz'uld or covering inclosing' the same, and to which they are suitably l'astened, substantially as shown and described.

3. In a eomluctor ot electricity, the combination of permanent magnets and pieces of attraetable metal placed in, eont-aetwith each other, a suitable inclosing' band or covering of insulating" material, and rivets or oth er suitable eond uetil )le fasten ings seeuri u said magnets and attract able metal to the upper portion of the covering, and being exposed above the top of the same, sul )stantially as shown and described.

-il-. In COllllJlIlttlO'l) with a ea r or other movable bodyearryin an idle-wheel, or described equivalent, a sc ional conductor of electricity insulated and resting upon said idle-whwlor the like, whereby movenumt ot' the ear or movable body will cause the eomluetor to be raised at thatpoint and its eontinuity to be broken, substz'uitially as and for the purpose set forth.

5. The combination, with a carer other movable body, of metallic brushes depending therefrom and electrically connected with each other through the ear, an idle-wheel, cam, or the l i ke carried by the earbetween thebrushes, and eleetirieal conductor composed of permanent magnets, attrzui'tal)le material placed alternately and in connection with each other, an insulating-eoverine' and comluetible fastenings securing said magnets and zlttraetaliile material to the insulation and extending above the same, all arranged substantially as and for the purpose set forth.

In testimony whereof I atlix my signatuie in presenee ol two witnesses.
